Problem-Solving Exercises
- Attendees will participate in problem-solving exercises that will help them to understand key aspects of wastewater pumping systems and lift stations. In-person participants are encouraged to bring laptops for in-class exercises, but laptops are not strictly required
For this course we will be collaborating with Gorman Rupp to have live pump demos and content from Gorman Rupp's Fundamentals of Pumping academy is included as part of the course.
